Issue 1: I have a fresh installation of Ubuntu 22.04 server on my RPi4 8GB and Install ROS2 Humble and tried this but still getting errors on my Python3 virtualenv. Do I need to build from the source?

ubuntu@ubuntu:~$ source 3d/bin/activate
(3d) ubuntu@ubuntu:~/ros2_ws/src/sdk-examples/python/oak/ros2$ python3 --version
Python 3.10.12
(3d) ubuntu@ubuntu:~/ros2_ws/src/sdk-examples/python/oak/ros2$ pip3 --version
pip 23.3.2 from /home/ubuntu/3d/lib/python3.10/site-packages/pip (python 3.10)
(3d) ubuntu@ubuntu:~/ros2_ws/src/sdk-examples/python/oak/ros2$ pip --version
pip 23.3.2 from /home/ubuntu/3d/lib/python3.10/site-packages/pip (python 3.10)
(3d) ubuntu@ubuntu:~/ros2_ws/src/sdk-examples/python/oak/ros2$ pip install spectacularAI
ERROR: Could not find a version that satisfies the requirement spectacularAI (from versions: none)
ERROR: No matching distribution found for spectacularAI

I even tried it on a different Ubuntu 20.04 desktop on my RPi4. I am getting a different issue there. If anyone faced a similar issue please help me out.

Issue 2:

ubuntu@ubuntu:~$ source vision/bin/activate
